First Clinical Study to Evaluate Safety, Tolerability & PK of DX243 in Healthy Volunteers and Patients With Hearing Loss
Recruiting now · Phase 2 · Has a placebo group
Conditions studied: Age-related Hearing Loss
In brief
Phase 2a: Multiple Ascending Dose (MAD) in male and female patients with hearing loss: The study will be conducted according to a randomised, placebo-controlled, double-blind design. A total of 24 patients, otherwise healthy, aged up to 75 years old, with mild to moderate hearing loss will be included. Two cohorts of 12 male or female patients (no ratio is required) will receive two different flat doses (low dose and high dose) ofDX243 or placebo for 29 days using SC administration. In each cohort of 12 patients, 4 will be randomised to placebo and 8 to DX243, so at the end of Phase 2a, 8 patients will have received placebo, 8 the low dose and 8 the high dose of DX243. The primary objective is to evaluate the safety and tolerability of DX243 administered subcutaneously after repeated doses. The secondary objectives are to detect preliminary signal of efficacy, using speech in noise tests, tonal and vocal audiometry, as well as tinnitus and quality of life.
